Amir Khan works-out at Gloves Community Centre in Bolton as he prepares for this weekend's fight

Warren said: "Amir is a quality fighter and if he is going places the Martin Kristjansens of this world are the kinds of opponents he has got to deal with - and he has got to deal with them in style.

"Making the world title fight is not a problem. It is about making the fight at the right time. That is why this is such a tough fight for Amir. If he comes through, then we will make the decision on what his next move is."

Khan is adamant he is ready for a crack at Campbell, who recently stunned Juan Diaz to claim the title, or interim belt holder Joel Casamayor who overcame Michael Katsidis.

But Khan has come to appreciate the need to keep himself focused fully on the job in hand and insists he will not entertain thoughts of Campbell until Kristjansen has safely gone the way of his 16 previous opponents.

Khan said: "I've trained hard just like I do for all my fights and I'm in the best condition I could possibly be in.

"I've got the strength and the speed and in every fight I am getting better and better."
